Several of my users are able to reproduce the following error consistently when they try to download a PDF from our site:

[26-Jan-2014 15:10:34 UTC] PHP Fatal error: Call to a member function getBestIssueId() on a non-object in ~/public_html/archives_ojs/plugins/generic/usageEvent/UsageEventPlugin.inc.php on line 195

The works correctly for me so I am trying to get more information from the user. They say they have used multiple browsers in OS X, Safari and Firefox. I am asking about what plugins they may have enabled but I really have no idea what is going on. It also worth noting that there are several other errors in my log that appear to be endemic to version 2.4.3.0. For example,

I was able to figure out why this was happening. I created a user for our subscribers that was supposed to be active on February 1st. So it had no subscription attached. Our subscription manager then accidentally gave out that user info and password to a new subscriber. When they logged in and tried to download a PDF, the site gave this error. However, it was only because no subscription was attached. They system should not be putting out a fatal error in this case, it should simply say there is not an active subscription. So I think it is a bug.
